l To all whom it 'may concern! scription of the same, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, Which'forni a part of this application.

This invention relates to improvements in. farm implements, and particularly to cultivators and beet diggers, the object of the invention being to produce a cultivator which can also be used for a beet digger, which cultivator can be adjusted to cut at a variety of predetermined depths, whereby if used for cultivators, the same can be used to cultivate the surface lightly for weeds or can be used to digat a great depth in order to turn the soil over to a greater degree. Also by such adjustment the same can be made to dig small beets or large beets without digging into an unnecessary amount of earth.

A further object of the invention is to produce a simple and inexpensive device, and yet one which will be exceedingly effective for the purposes for which it is designed.

One of the particular points of the invention is the improved method of lifting the cultivator or digger from the ground, as

. will appear.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

Inthed-rawings similar characters of reference indicate corresponding parts in the several views. a

Figure 1 is a side elevation of the complete implement showing how it can be connected with a traction engine or other draft means. Fig. 2 is a rear elevation of the complete implement. Fig. 3 is a fragmentary view in section showing the means of applying the digging points or blades. Fig. 4 is a top plan view of the forward end of the frame of the implement. Fig. 5 is a top. planview of a modified form of blade shown n the other views.

Referring now more particularly to the characters of reference on the drawings, 1'- first provide a mainframe 1, provided with a projecting tongue member 2.

F The numeral 3'designates the wheels of the 1mplement mounted on upwardly inc 'ning shafts 4, having a cross shaft 5 at ts upper end turnably journaled in a bear- 1ng-6 on the top of the frame 1. This shaft is provided with an upwardlyprojecting lever 7 moving through a quadrant 8 provided with a plurality of holes 9 in which f the lever 7 may be fixed in a predetermined position by a pin 10.

The rear end of the frame 1 is provided a with a plurality of spaced'bars 11 between which are bolted downwardly projecting bars 12 having the lower portions projecting at an angle as at 13, and carrying beveled blocks 14. On each of. the blocks 14 is mounted a double edged blade 15. having one bolt 16 projecting therethrough and having an upwardly projecting stud 17 adaptedto project into either one of two orifices 18 spaced on each side of the bolt 16. Either one of these orifices may be used accordingly as one edge of the blade is turned to the outside or inside respectively. This stud holds the blade rigid with respect to the block 14 without the necessityof using two bolts.

The forward end of the tongue 2 is provided with a pin 19 adapted to fit into any one of the holes 20 in a clevis 21, suitably connected to the traction engine or other draft'means 22.

Forthe purpose of raising or lowerin the blades 15 I provide a spool or nigger-Tread 23 keyed to a shaft on the engine 22. Over this is thrown oneor more turns of rope or cable 24 connected with the lever 7. When it is desired to lower the blades, as shown by dotted line in Fig. 1, the pin is removed from the quadrant and the weight of the frame causes the wheels to move forward, thus lowering the frame 1 and its connected parts, including the blades 15, all as shown by the dotted lines in Fig. 1. In order to raise these blades the loose end of the rope is pulled tight on the spool or Nigger-head, and the latter revolving draws the lever 7 back to its former position, which presses the wheels 3 downward, and raises the frame 1 and its-connected parts. This is the predi fli fi 'm s a' nd"ha e ng? frame, but otlier methods-of aticonipl is' this end may be used, such as a frictiou'eon 5 r d drum HSlZQMlEIQiILQLQZ Q YQQQ PQQI1D nigger-head. The lever 7 may 'be fixe by in 10 in any desired osttio zttoa-make.
